OXC

OXC is a bet that JavaScript tooling should be 100x faster. Built in Rust by the team behind Biome contributors, it's a parser, linter, formatter, resolver, and transformer — all in one project, all blazingly fast. Think of it as the "rewrite everything in Rust" movement applied to your entire JS toolchain.

The linter alone is 50-100x faster than ESLint. The parser is used by Biome and Rolldown (Vite's future bundler). If you're tired of slow CI pipelines and linting that takes minutes, OXC is the future arriving early.

Biome is the closest alternative — also Rust, also fast, but focused on formatting and linting. ESLint is the incumbent with the ecosystem but can't compete on speed. Prettier is formatter-only and JavaScript-speed.

Best for teams with large codebases where lint/format time actually hurts. If you're a solo developer with a small project, ESLint is fine.

The catch: it's still maturing. Not all ESLint rules have equivalents yet, and the ecosystem of plugins is thin. You're betting on the future, not the present.
